Interesting theory - albiet completely false.
Committing perjury is hardly an example of free speech. You swear to tell the truth, yada yada yada, and then lie? That causes direct harm to another person thereby violating HIS rights - hence, it isnt a 1st Amendment issue. Remember, your rights end when your exercise of them infringes upon anothers rights.
Same thing with child porn. The perpetrators of that are committing a direct violation of a child and causing him harm. As you have no right to harm another, this is certainly NOT a protected expression of your right to a free press.
You want to try again?
No, you proved my point. Rights are not absolute. We do not have an absolute right to freedom of speech. We do not have an absolute right to freedom of press. We do not have an absolute right to keep and bear arms.
You can not legally commit perjury, produce child porn, or own a nuclear missile. Why? Because your right of freedom of speech (not free speech but freedom of speech, it is an important distinction), freedom of press, or right to keep and bear arms, like all rights, is not absolute.
Why don't you try again.
